5.4. Dating methods

Dating methods

To know the history of the Earth it is necessary that we order the events that we know.

Events or materials can be dated using two types of dating methods:

  • Relative dating: It consists of ordering rocksfossils or events from the oldest to the most modern, without specifying their age.
  • Absolute dating: It consists of putting a date to the materials or events, that is, specifying the years they are.
